I started by selling everything at home that I bought and didnt want to watch anymore. This quickly ran out in a matter of weeks. The first mistake I made looking for Dvds was to pay to much for the movie and than have to lose money on E-Bay selling it. You have to do your research both in Half.com and E bay and continuosly check what the prices are for Popular movies as like the stock market the supply and demand moves Up and down constantly. I started selling allot of National Treasure movies when the price was near $9.00 but as the supply became more abundant the price came down to $6 or $7. My best sources I found for looking for Dvd s are my local Video rental stores and making a deal with the owners to buy most of what they are overstocked on. When you think about it thier Supply and demand goes up and down too!! By me buying from them they dont have to sell thier product in 200 different transactions and take up valuable retail space. They sell to me all in one lot and they get rid of all the movies that are overstocked. Flea markets also tend to have allot of used Dvds to sell but you have to look carefully and buy smart. I always bring my Cell Phone with Innternet to check certain Dvd prices befor I buy. Thanx for reading my review..Norman
